Do you know these symptoms of poor kidney function?

Some people simply think that as long as they have lower back pain, it means their kidney function is poor. In fact, this can be seen from the changes in urine volume. Normal people urinate 1000-2000 ml per day, with an average of 1500 ml. Whether the urine volume increases or decreases, it may be a manifestation of kidney disease. In addition, the disease can also be discovered from changes in urine characteristics, edema, nausea, vomiting and other digestive tract symptoms.

1. Changes in urine volume

A normal person urinates 1000-2000 ml of urine per day, with an average of 1500 ml. Whether the amount of urine increases or decreases, it may be a manifestation of kidney disease. Especially for normal people, who rarely urinate at night, if you find that you have to get up several times at night and do not drink much water before going to bed, you should be more alert to kidney disease.

2. Changes in urine characteristics

The normal urine color is transparent light yellow. If you drink less water or urinate for the first time in the morning, the color will be slightly darker. If your urine is red or contains a lot of foam, you should go to the nephrology department for a check-up.

3. Edema

The kidneys are the organs that metabolize water in the human body. If the kidneys are not healthy, water will accumulate. Some people find that their eyelids, or feet and legs are swollen when they wake up in the morning. They should consider kidney problems.

4. Gastrointestinal symptoms such as nausea and vomiting

When kidney disease develops to the end stage, it will affect gastrointestinal function, leading to symptoms such as nausea, vomiting, and loss of appetite. Therefore, if these symptoms occur, in addition to seeing a gastroenterologist, you should also pay attention to ruling out kidney disease.

5. Itchy skin

For patients with end-stage renal disease, urea in the body cannot be excreted through urine and will be excreted through the skin, thereby irritating the skin. In addition, toxins accumulated in the body can lead to peripheral neuropathy and also cause skin itching.

Some of the above signs of kidney disease occur in the early stages, while others are already manifestations of the late stages. Therefore, it is not enough to rely solely on symptoms to judge whether your kidneys are healthy. "We must attach importance to physical examinations, especially for the elderly and high-risk groups with diseases such as hypertension, diabetes, and abnormal blood uric acid."
